IOS App Basics

1). Info.plist:iOS through it and app interaction

the Info.plist file contains metadata about your apps, which the system uses to interact with your app.

The Information property List File

Xcode uses information from the General, capabilities, and Info tabs of your project to generate a information property List (info.plistat Compile time. The info.plist file is a structured file, contains critical information about your A PP ' s configuration. It is used by the app Store and by IOS to determine your App's capabilities and to locate key resources. Every app must include this file.

Whenever possible, use the general and Capabilities tabs to specify the configuration information for your app. Those tabs contain the most common configuration options available for apps. If you don't see a specific option on either of those tabs, use the Info tab.

2). A Declaration of the app ' s required capabilities:

The app Store uses this information to determine whether or not a user can run your App on a specific device.
